The YRT turntable bearing consists of a thrust/centripetal race, a thrust/central shaft collar, a thrust washer, two needle roller cage assemblies and a set of centripetal cylindrical rollers. The race and the collar have evenly distributed mounting screw holes. This type of bearing has high axial and radial load carrying capacity, high tilt stiffness and high precision. Suitable for rotary tables, as well as bearing configurations for measurement and experimentation. This type of bearing has higher requirements for the matching equipment parts. Control the tightening torque of the mounting screws during installation
Scope of application: It is widely used in precision rotary table, vertical grinder, indexing head, gear hobbing machine, milling machine workpiece shaft and other precision devices.
The thrust-central combination structure can withstand biaxial axial loads, radial loads and overturning moments. The bearing is provided with mounting holes, which can be directly fixed to the bearing by bolts; the bearing has been preloaded at the factory, and the installation does not need to adjust the clearance; this series is used for low speed, short running cycle and high rigidity and precision. Occasionally, such as rotary table, indexing head, etc.
The external structure is the same as the YRT series, but the internal structure is different from the YRT series, which determines that the series has higher limit speed than the YRT series, and the friction torque is lower and uniform than the YRT series. Therefore, it requires relatively low friction but relatively high speed. In this case, the series can be used, such as bearings used for shafts driven by direct drive motors.
The ZKLDF thrust angular contact ball series can also withstand combined loads, but with extremely high speed and extremely low friction torque, while ensuring high rotational accuracy. Ideal for applications with such requirements, such as high-speed rotary tables, milling, grinding, and precision measurement, measuring equipment, etc.
Based on YRT rotary table bearings, this series of bearings is equipped with an angle measuring system on the YRT rotary table bearings to accurately measure and adjust the angle of bearing rotation to ensure high-precision operation of the machine.
The measuring system consists of a sensor component and a measuring rule. Using purely inductive measurement principle, the signal is extremely accurate and the measurement accuracy is high. At the same time, due to the use of high protection measures, the measuring system is not subject to external interference during operation, such as dust smoke, mild oil stains and scratches, magnetic fields, etc. It is reliable in operation, does not require excessive maintenance, and has a wide application range. It can be applied to high-precision rotary tables and rotating shafts, indexing heads, military radars, aerospace, aerospace, and fields requiring high angular rotation accuracy in measurement and test.
